In the meantime, the electric power sector has
measures available today that could lead to mercury
reductions of between twenty and eighty per
cent. Two of the most important immediate steps
include the adoption of the best available control
technologies and investments in energy efficiency.
Mercury control devices are being introduced
successfully at regulated waste incinerators in
Canada; however, these technologies are still in
the early stages of development for coal-fired
The presence of chlorine in alternative fuels (e.g., sewage sludge, municipal solid waste
or incineration ash, chlorinated biomass,) has both direct and indirect implications on
cement kiln emissions and performance. Methods have been developed to properly
manage chlorine and its potential implications – but it is important that these implications
be recognized and managed. Trace levels of chlorine in feed materials can lead to the
formation of acidic gases such as hydrogen chloride (HCl) and hydrogen fluoride (HF)
Waste incinerators fall somewhere between the two
categories of incidental and deliberate emissions. Similar
to a coal plant, they burn a feedstock — in this case
garbage — and mercury is released as an incidental
emission. The difference is that most of the incidental
emissions from waste incinerators are a result of mercury
that is deliberately put into products. These may include
fluorescent lamps, old batteries, dental office waste, electrical
switches or thermostats.
Donor must adhere to the Zanzibar medicine, medical supplies and medical equipment
donation guidelines so that donations will address the expressed needs of the Zanzibar and
that the date of expiry should not be less than one year unless there is a clear evidence from
Zanzibar that there is clear logistics and managerial capacity to store and distribute shorter
dated drugs efficiently.
The cost of disposal of waste pharmaceuticals
Pharmaceuticals are ideally disposed of by high temperatures (i.e. above 1200
